A heavy-lift launch vehicle (HLV) is an orbital launch vehicle capable of lifting payloads between 20,000 to 50,000 kg (44,000 to 110,000 lb) (by NASA classification) or between 20,000 to 100,000 kilograms (44,000 to 220,000 lb) (by Russian classification) [1] into low Earth orbit (LEO). [2]
A diagram of the Shuttle-Derived Heavy Lift Launch Vehicle, Block I configuration. The HLV was proposed to be a 4,600,000 pounds (2,100,000 kg) vehicle at liftoff with two 4-segment Space Shuttle Solid Rocket Boosters weighing about 2,600,000 pounds (1,200,000 kg) providing a total thrust of 5,900,000 pounds-force (26 MN) at sea level and the Space Shuttle External Tank weighing about ...
The Shuttle-Derived Heavy Lift Launch Vehicle ("HLV") was an alternate super heavy-lift launch vehicle proposal for the NASA Constellation program, proposed in 2009. [74] A 1962 design proposal, Sea Dragon, called for an enormous 150 m (490 ft) tall, sea-launched rocket capable of lifting 550 t (1,210,000 lb) to low Earth orbit.
A potential heavy-lift variant (HLV) of the ULV, in theory was capable of placing up to 10 ton class of spacecraft into Geosynchronous Transfer Orbit. It was planned to include: [22] A larger dual S-250 solid strap-on boosters as compared to the S-200 boosters used in LVM3;

The model HP-25C, introduced in 1976, addressed that shortcoming through the first use of battery-backed CMOS memory in a calculator, termed continuous memory by HP. Like all early HP calculators, the 25 used the Reverse Polish Notation (RPN) for entering calculations, working on a four-level stack (x,y,z,t). Nearly all buttons had two ...
